Official results of the election, released on June 13, have sparked the most widespread street protests in Iran since the country's 1979 Islamic revolution.

The defeated candidates have submitted a total of 646 complaints about the election.

Earlier this week, a Guardian Council spokesman said one common complaint was that the number of votes surpassed eligible voters in some constituencies.

But the spokesman, Abbasali Kadkhodai, said it may have been due to the fact Iranians could vote wherever they wanted and that in any case it would not have had any major impact on the election result.

The council is a 12-man body, six senior clerics appointed by the Supreme Leader and six Islamic jurists, which must ensure all laws agree with Islamic Sharia law and Iran's constitution.

It also vets aspiring candidates for presidential elections and must approve the election results.
